General description In constructing the machine I have employed thekeyboard, selecting mechanism and the registration control mechanismcomprising the digitation mechanism, the transfer mechanism and thereversing mechanism employed in the Friden calculating machine. For acomplete disclosure of this part of the mechanism reference is to be hadto the patent to Friden 2,229,889, issued January 28, 1941. This portionof the mechanism will be described first and thereafter I will describehow this basic registration control mechanism i utilized to causeregistration in any selected one of a plurality of totalizers and in agrand totalizer.

Referring to Figure 1, the machine is provided with a suitable casingI00 and has a conventional keyboard IIlI comprising a plurality of rowsof numeral keys numbered 0 to 9. A plurality of totalizers III, H2, H3,H4, H5, H5, Ill, H8, H9 and a grand totalizer I20 are arranged in a rowat the top of the machine and have dials bearing numerals which arevisible through suitable windows provided in the casing I00. After anumber has been set up on the keyboard IEII the operator determines inwhich totalizer the number is to be registered and for this purpose aseries of totalizer keys I2I, I22, I23, I24, I25, I26, I21, I28, I29 areprovided, also the item may be registered additively or subtractively inthe selected totalizer by setting the lever I30 either in the add orsubtract position. For example, if

the lever I30 was set in the add position and a number had been set onthe keyboard lilI when the operator depressed the totalizer key I23 thevalue set on the keyboard would be additively registered in thetotalizer H3, and it would also be additively registered in the grandtotalizer I20. If the lever I39 had been set in the subtract positionthe value would be subtractively registered in the selected totalizerand in the grand totalizer so that during a series of registeringoperations, assuming all of the totalizers had been cleared at thebeginning of the operation, the grand totalizer will indicate the sum ofall the totals in the individual totalizers III to II9.

At the same time that the value set in the keyboard is registered it isprinted on a paper tape ISI which appears in a Window I32 in the casing.As shown in Fig. 1 the item 217.23 had been set on the keyboard NH andthe totalizer key I29 had been depressed with the control lever I38 inthe subtract position, the figure 9 at the left edge of the tapeindicates the number of the totalizer in which the value 217.23 wasregistered and the sign of the registration is indicated by the minussign thereafter. The printing mechanism which will presently bedescribed is indirect in operation, that is, all of the printingmechanism is disposed below the tape IIiI. This method of printing wasfirst disclosed and claimed in my co-pending application Serial No.502,379, now Patent No. 2,405,562 issued August 13, 1946.

When the operator desires to take an individual total he moves thecontrol lever ass to the total position and copies the figure appearingin the individual totalizer to the keyboard and presses the associatedindividual totalizer key. This causes the value to be subtracted fromthe individual totalizer thereby clearing the individual totalizer, butthe figure is not subtracted from the grand totalizer, and the totaltaken is printed on the tape I3I. In order to take a grand total thesame procedure is followed and the grand total key I49 is depressed.This causes the figure standing in the grand totalizer to be subtracted,thereb clearing the grand totalizer.

If desired, my machine can be employed as a cash register and for thispurpose is provided with a cash drawer I4I.

Having now described in general the arrangement and operation of mymachine I will explain its construction in detail.

Registration control mechanism Referring to Fig. 2, depression of thenumeral key I42 in the keyboard IQI causes differential movement ofeither of two slides I43, I46 which move selector gears i 15, I 26 inthe path of segmental gears M-I secured to actuator shaft M8 so thatupon rotation of the shaft I48 a square shaft I52, on which the selectorgears I45 and I46 are mounted will be rotated a differential amountcorresponding to the key I42 depressed. This is the digitation part ofthe registration and occurs in the first part of the cycle. The transferoccurs in the latter part of the cycle and is efiected by shifting thetransfer gear IEI, which is mounted on the square shaft I56, into thepath of a transfer toot I52 on the actuator shaft I48. This causes theadded increment of "1 to be imparted to the square shaft I58. Theactuators shafts I48 are driven by means of bevel gearing from driveshaft I53 which is uni-directional in operation so that the squareshafts I58 are also uni-directional in operation. In order to obtainpositive or negative registration, a reversing gear is employed whichcomprises a pair of bevel gears I54, 255 integrally connected by asleeve I'Bt slidable on the square shaft I59. As shown, the gear IE4 isengaged with a bevel gear I52 (see also Fig. 3) which is secured to apinion I58 (Fig. 2) which is constantly in mesh with a pinion I59rotatable on a sha t E55. Secured to the shaft ItIl are a series of armssea, one for each reversing gear I5 3, I so that rotation of the shaftI69, in a clockwise direction in Fig. 2, will cause shifting of thereversing gears I54, I55 to engage the bevel gears I55 with the bevelgears I5? to cause positive registration. As shown in Fig. 2 thereversing gear is in the negative registration position.

The registration control mechanism described above is substantiallyidentical to the aforementioned patent to Friden 2,229,889.

Sign control In this machine the sign control is pro-set prior toregistration and comprises the lever I30 (Figs. 1 and 11) which as shownis in the subtract position. This lever is pivoted in the framework atI62 and is connected by a link I63 with a plate I64 rotatably mounted onthe shaft I60. The shaft I has secured thereto an arm I55 provided witha pin I66 which is normally held in engagement with a hook IE'I on theplate I64 by a spring I63. The plate I54 is provided with a detent I69.As shown the parts are positioned in the subtract position. In order todetermine additive registration the control lever I39 is movedrearwardly, that is clockwise in Fig. 11, which causes the plate I64 tobe rotated clockwise and the hook Ifi'I engaging the pin I56 rotates thearm I65 and shaft I66 clockwise. This causes shifting of the reversinggears I5 II55, as previously described, to the additive position. If thecontrol lever I38 and the reversing gears ISL-I55 are in their additivepositions, and the lever I30 is then rocked to the subtractive positionshown in Fig. 11, the pin IE6 on the arm I55 is held against the hookIBl by the spring I58, thus causing the arm I65 and shaft I66 to followthe plate I64 and rock counter-clockwise. This will shift the reversinggears IS S-I55 to the position shown in Fig. 2.

Drive The machine is provided with a motor I10 (Fig. 4) whose armatureshaft III has a worm I12 thereon engaging a worm wheel I13. The wormwheel I13 is connected by means of a sleeve I14 to a ratchet wheel I15(Fig. 5) of a pawl and ratchet clutch I76. The pawl III of the clutch isnormally held disengaged from the ratchet wheel by a control lever H8pivotally mounted at H9. Clutch control lever I78 is connected by a linkI80 to a lever I8I having pin and slot connection I82 with a lever I83having a fiber pin I84 therein which extends through an opening in theframe (Fig. 9) for operating the motor switch I85. A spring I86 (Fig. 5)normally urges the parts to the position shown where the switch I85 isopen and the clutch HE is disengaged. Clockwise rotation of the controllever I "I8 (Fig. 5) by means hereinafter described causes closure ofthe switch I65 and engagement of the clutch The driven side of theclutch is secured to the previously described transversely extendingmain driveshaft I53.

Totalizers The machine is provided with a plurality of 5.. itemtotalizers III to H9 and a grand totalizer I20. All of these totalizersare of substantially identical construction although they may vary incapacity, so that a description of one will suffice. Each totalizercomprises a plurality of numeral wheels I8'I (Fig. 2) each having a spurgear I88 secured thereto. The numeral wheels are rotatably mounted on ashaft I89 which is supported in a pair of bellcranks I90, I9I (see Fig.7). The bellcranks I90, I9I are identical in shape and are rigidlyconnected together by tie rods I92, I93, I94, I95, I99, I91, I98 and asleeve I99. The sleeve I99 is rotatable on a fixed shaft 200. It will beunderstood that each of the totalizers is similarly mounted, each in itsown supporting framework, the several supporting frames beingindividually rotatable about the shaft 200.

Registration transmission mechanism It will be recalled that theconventional regis tration control mechanism has been described ascomprising a keyboard IOI (Fig. 1) having six rows of keys which controlthe setting of digitation gears I45, I46 (Fig. 2) on square shafts I50,of which in this instance there are six, one for each row of keys, andthat each of these shafts is provided with a transfer gear I5I and areversing gear so that in each order of the registration controlmechanism means are provided for selectively controlling thedifferential rotation and direction of rotation of a gear I59. There aresix gears I59 on the shaft I60. In order to selectively transmit therotation of these gears to any selected totalizer and the grandtotalizer a registration transmission mechanism is provided. Thiscomprises a plurality of series of ordinal actuator gears, there beingone series for each totalizer, and means for causing like movement ofall gears of like order. For example, associated with totalizer I I3(Figs. 1 and 2) which has a capacity of six orders, there are sixactuator gears 20I, 202, 203, 204, 205, 206 (Figs. 2 and 6), the gear20I being in the units order, the gear 202 in the tens order, etc. Allof the units order gears 20I are geared together by means of pinions 2II on a square shaft 2I2. For example the units order actuator gear intotalizer H3 is connected to the units order gear 20I and th totalizerII5 by means just described a can be seen in Fig. 7. Similarly, the gear202 in the tens order of totalizer H3 is connected to the tens ordergear 202 in the totalizer I I 5 and to all other tens order gears bymeans of pinions 2I3 on square shaft 2I4. All of the hundreds ordergears 203 are connected together by means of pinions 2 I5 on squareshaft 2I6. All of the thousands order gears 204 are connected togetherby pinions 2I'I on a square shaft 2I8; and all of the tens thousandsorder gears 205 are connected together by pinions 2I9 on a square shaft220. As previously stated, the totalizers may vary in capacity. In theform shown, the item totalizers I I I, II2, II4, H5, H0, H1, and I I8all have five orders, and item totalizers II3, H9, and grand totalizerI20 all have six orders. The pinions 2II, 2I3, 2I5, 2II, and 2I9, and.the square shafts 2I2, 2M, 2I6, 2I8, and 220 just referred to providefor concurrent operation of the actuator gears 20I, 202, 203, 204, and205 of corresponding orders of the first five orders of each itemtotalizer and the grand totalizer. The sixth order actuator gears 206,in the item totalizers I I3, H9, and the grand totalizer I 20 only, areoperatively connected by pinions 22I on a square shaft 222. Theregistration transmission mechanism receives its motion in the followingmanner. The square shaft I50 in the units order, that is, the squareshaft asso-' ciated with the units order in the keyboard, transmits itsregistering movement to the pinion I59 in mesh with the units order gear20I in the totalizer H8 and this motion is transmitted via the pinions2I I on the square shaft 2 I2 to all the units order gears 20I in theother totalizers including the grand totalizer. The square shaft I50associated with the second order of the keyboard transmits its motion tothe actuator gear 202 in the totalizer I I1 which in turn transmitsthesame motion via the gears 2I3, the square shaft 2I4 to all the othertens gears 202, etc. It will be understood that for every revolution ofthe main drive shaft I53 the differential rotation of the shafts I50 istransmitted to all of the actuator gears so that, for example, all ofthe units order gears 20I rotate in unison, all of the tens order gears202 rotate in unison, etc.

Totalizer keys The totalizer gears I83 (Fig. 2) are all normally out ofengagement with the differential actuator gears. If it is desired tocause registration in a selected totalizer, for example, the totalizerII3, the item is first set up on the keyboard IOI, the lever I30 is setto the desired add or subtract position and then the key I23 isdepressed. The key I23 (Fig. 2) is pivotally mounted at 24 and isconnected by a spring I25 to the tie rod I91 so that rocking the key I23clockwise through the urgency of the spring I25 rocks the framework inwhich the totalizer is mounted counter-clockwise about the shaft 200,engaging the gears I88 of the totalizer with the actuator gears. Adetent 223 which normally centralizes the numeral wheel and restrains itfrom rotation is removed from engagement with the gear I33 when theframework is rocked counter-clockwise by a fixed transversely extendingrod 224. The engagement of the detent 223 with the rod 224 normallyholds the associated actuator framework I9II-I9I in the inactiveposition shown in Fig. 1.

Depression of the key I 23 also initiates the drive as will now beexplained. Each of the item totalizers III to H9 has associatedtherewith a plate 230 rotatably mounted on a shaft 23I and urgedclockwise by a spring 232. The construction and operation of theseplates is the same with respect to each totalizer so a description ofone will suflice. Referring to Fig. 2, the plate 230 has a shoulder 233which engages the tie rod 592 to latch the plate 230 in its Fig. 2position and to assist in holding the totalizer framework in theposition shown, that is, with the totalizer gears out of mesh with theactuator gears. However, upon depression of the key I23 the rod I92 isremoved from contact with the shoulder 233 and the spring 232 rotatesthe plate 230 clockwise so that a shoulder 234 engaging a roller 235 onan arm 236 secured to a shaft 231 causes counter-clockwise rotation ofthe shaft 23?. Each plate 230 has an arm 236 associated therewith andall of the arms 233 are secured to the shaft 231. The right end (Fig. 5)of the shaft 231 has secured thereto an arm 238 having pivotallyconnected thereto link 239 which has a pin and slot connection 240 atits forward end with a clutch control lever I'I8. Thus it will be seenthat depression of the key I23 (Fig. 2) will unlatch the spring-urgedplate 230 which rocks the shaft 237 counter-clockwise causing th link239 (Fig. 5) to be drawn rearwardly to rock the clutch control 7 arm I18clockwise and cause closure of the switch and engagement of the clutchwhereupon the shaft I53 rotates.

The registration transmission mechanism is normally locked. Referring toFig. the actuator gears such as 203 associated with the grand totalizerI are constantly in mesh with pinions 2M integral with gears 242 whichare locked by a bail 243 pivoted at 24 3. One arm 245 of the bailappears in Fig. 5, the other arm 246 appears in Fig. 4. The bail 243 isnormally urged counter-clockwise (Fig. 4) by a lever 241 pivoted at 244having pin 248 which engages the arm 245, the lever 251 being urgedcounter-clockwise by the spring ate. In the full cycle position of theclutch, a cam 2.58 secured to the main drive shaft I53 engages a pin Iin the lever 241 which, through a spring 252 urges the bail 243clockwise (Fig. 4) or counter-clockwise as viewed in Fig. 5 to lock thegears 242 and thereby lock the entire registration transmissionmechanism. However, as soon as the clutch I16 is engaged the cam 250(Fig. 4) rotates and the lever 241 is free to move under the influenceof its spring 249 thereby withdrawing the locking bail 243. Rotation ofthe shaft 53 causes operation of the registration control mechanism andthrough the registration transmission mechanism just described causesentry of the value set in the keyboard Illi in the selected totalizer.

This occurs during the digitation phase of the first part of the cycle.The transfer occurs in the latter part of the cycle. It will be recalledthat the transfer movement is transmitted to the shaft I (Fig. 2) by atransfer gear i5I having been moved into the path of the transfer toothI52 on the actuator shaft I48.

In accordance with my invention a single series of ordinally arrangedregistration control mechanisms, that is, the square shafts I50 and thepinions I45, it and I thereon serve, through the registrationtransmission mechanism previously described, to service any selectedtotalizer. This is true not only of the digitation part of theregistration, but the transfer part also as will now be described.

When any selected totalizer, such as totalizer H3 (Figs. 2, 6 and 8), ismoved into engagement with its actuator gears by depression of the keyI23, a transfer tooth 250 on the numeral wheels in the totalizer, exceptthe highest order, is moved into cooperative relationship with atransfer lever 26I pivoted on a shaft 252. All of the transfer levers2I3I associated with the units order numeral wheels in the totalizersare secured together by transversely extending rods 253 and also rigidlysecured to the rods 263 is a lever 254 (Fig. 8) having a pin 265 whichengages the flanged portion 266 of the transfer gear I5I on the squareshaft I50 in the tens order. From this it will be apparent that wheneverany totalizer is in registering position and the units order numeralwheel passes through 0 to 9 position the associated transfer lever 26Iwill cause rocking of the rods 263 and the lever 264 to move thetransfer gear I5! in the tens order of the registration controlmechanism to operative position so that in the transfer phase of thecycle a trans fer movement will be transmitted from the tens ordersquare shaft 15a through the registration transmission mechanism to thetotalizer in registering position.

Similarly, the numeral wheels in the tens order of the totalizers havetransfer teeth adapted to cooperate with transfer levers 261 which arerigidly connected together by transverse rods 268 having secured theretoa lever 269 (Fig. 8) which serves to set the flanged portion 266 of thetransfer gear I5I in the hundreds order of the registration controlmechanism. In this same manner transfer mechanism is provided for thehigher orders of all the totalizers.

In each registering operation of the machine the main drive shaft I53revolves twice. During the first revolution the value set in thekeyboard "H is registered in the one of the item totalizers Ill to II9which has been selected by depression of one of the keys I2I to I29. Inthe second revolution the same value is entered in the grand totalizerI20.

The main drive shaft I53 is automatically caused to rotate twice by thefollowing mechanism. The main drive shaft I53 (Fig. 9) has a pinion 21Eengaging a gear 21I having a pin 212 thereon. The gear 21I rotates oncefor two revolutions of the pinion 210 so that prior to the conclusion ofthe first revolution of the shaft I53 the pin 212 engages an arm 213pivoted to the frame at 214 and rocks it clockwise. The arm 213 has apin 215 secured thereto which passes through a slot in the frame 215 andengages in a slot 21E of a link 211 (Fig. 5) pivoted at 218 to theclutch control lever I18. When the clutch control lever I13 is rockedclockwise (Fig. 5) to engage the clutch the link 211 is drawn forwardly,moving a tail 219 thereon forwardly of a fixed pin 2% so that when inthe course of the first cycle the pin 215 moves upwardly, it disposesthe tail 2'55 in front of the pin 250 thereby locking the clutch controllever I18 from disengaging the clutch at the end of the firstrevolution. As will be evident in in Fig. 9, in the course of the secondrevolution the pin 212 releases the lever 213 that the tail 21s (Fig. 5)is lowered below the pin 28% by gravity or by a conventional restoringspring (not shown) so that at the end of the sec-- ond revolution thespring I86 may move the clutch control lever I13 counter-clockwise todisengage the clutch.

At the conclusion of the first revolution the item totalizer isdisengaged from the actuator gears. This is accomplished by thefollowing mechanism. The main drive shaft I53 (Fig. 10) has a pinion 2g!secured thereto engaging a gear 282 which meshes with an idler gear 283engaging a gear 2% secured to a cam 285. This gear train causes onerevolution of the cam 285 for two revolutions of the shaft 553. Cam 235is shown in the full cycle position of the parts, and after rotationclockwise engages a roller 28% on a belicrank 228? connected by a link282 with an arm 253d secured to shaft 23? causing the shaft 23? to berocked counter-clockwise as viewed in Fig. 10, or clockwise as viewed inFig. 2.

This clockwise rotation of the shaft 231 causes the arms 236 to rotateclockwise (Fig. 2), and the plate 230 associated with the totalizerwhich had been in the operative position is rotated counter-clockwise.The plate 220 has a portion 290 which moved under the rod I92 when theplate 230 was unlatched. and this portion served to hold the totalizergears in engagement with the actuator gears. When, as just described,the plate 239 is moved counter-clockwise it releases the rod I92 and aportion 295 engages the rod I92 and positively rocks the totalizersupporting framework clockwise to remove the totalizer gears fromengagement with the actuator gears. At the end of the second revolutionof the shaft I53 (Fig. 10), or at the end of the revolution thereto.

of the cam 285, the roller 286 is free and the plate 230 (Fig. 2)returns to the position shown under the influence of a spring 232.

Grand totalizer At the beginning of the second cycle of the -main driveshaft I53 (Fig. 4) the grand totalizer is automatically moved toregistering position. The shaft I53 has a pinion thereon (not shown)engaging a gear 292 having a cam 293 secured The cam 293 makes onerevolution for every two revolutions of the shaft I53. Cam follower 294is rocked counter-clockwise on its pivot 295 after the cam 293 isrotated 180 clockwise. The cam follower 294 normally engages a pin 236on a member 291 resiliently mounted on a link 2% pivoted to the tie rodI96 of the grand totalizer supporting framework. By means presently tobe described, the pin 296 is normally disposed in cooperative relationwith the cam follower 294 as shown in Fig. 4 so that earn 203, throughthe action of the cam follower 294, causes the totalizer I20 (Fig. 5) tobe moved into engagement with its actuator gears during the secondrevolution of the drive shaft I53. During this revolution the value setin the keyboard IN is registered in the grand totalizer I and in thelatter part of the second revolution any transfers which may occur inthe grand totalizer are effected in the same manner and by the samemeans already described. Thus it will be seen that the registrationcontrol mechanism serves during the first cycle of the operation tocause registration in one of the item totalizers III to H9 and duringthe second revolution controls the registration of the same value in thegrand totalizer I20 and also effects any transfer which may occur there.

Taking totals In order to take a total from any totalizer the controllever I (Fig. l) is moved to the total position. Usually in a businessmachine of this character total taking is done at the conclusion .of arelated series of operations, as for example,

at the conclusion of a days work so that usually all of the totalizersare cleared one by one. In this machine totals are taken by copying thenumber from the totalizer to the keyboard and then depressing thetotalizer key. This causes,

in the case of the item totalizer, subtraction of the value from thetotalizer leaving the totalizer clear, but without subtracting the valuefrom the grand totalizer. This, of course, is to preserve the grandtotal. As previously described, during registering operations when thecontrol lever I30 is either in the add or subtract position itemsregistered in any selected item totalizer are also registered in thegrand totalizer.

Referring to Fig. 11. When adjusting the con trol lever I30 to the totalposition it is moved counterclockwise from the position here shown. Thiscauses counterclockwise rotation of the plate I64. If the lever I65 isalready in the subtract position, as shown, it will remain there, thehook I61 merely leaving the pin I66. If the plate I64 and the arm I65are in their add positions, and the'plate I64 is rockedcounter-clockwise to the total taking position, the spring I will causethe lever I to follow, thereby rocking the shaft I60 counter-clockwiseand shifting the reversing gears ltd-455 to the subtract position shownin Fig. 2. If, at the start of this operation, the arm I65 should notrespond to the pull of the spring I68, a shoulder 300 on the plate 10I64 will engage the pin and positively start rocking of the arm I65 andshaft I60.

It will be recalled that the shaft I60 controls the registeringmechanism as well as the reversing gears. Therefore, with the controllever I30 in the total position, values copied from the item totalizersIII to H9 (Fig. 1) to the keyboard IOI, will, upon depression of thetotalizer keys I2I to I29, subtract the totals therefrom.

While totals are being taken from the item totalizers, the grand totalis maintained in the grand totalizer I20 by the following mechanism.Referring to Fig. 4, it will be recalled that the automatic movement ofthe grand totalizer to registering position depended upon the pin 296being in cooperative relation with the follower 294. Referring to Fig.11, the pin 296 is normally urged to this position by a spring 30I whichholds the pin against the side of a slot 302 in the frame. The pin 296is disposed in the lower forked end 303 of a lever 304 pivoted at 305having a shoulder 306 and a pin 30'! thereon. When the lever I30 ismoved counter-clockwise from the position shown in Fig. 11 the link I63is moved to the left. This link has a lever 308 pivoted thereto at 309and urged counter-clockwise by a spring 3I0 so that the upper edge ofthe lever 308 engages the pin 301. When the link I63 is moved to theleft, a shoulder 3II on the lever 308 engages the pin 30! and rocks thelever 304 counter-clockwise to move the pin 266 rear- Wardly so that itis moved out of cooperative relation with the follower 294 (Fig. 4).

To take a grand total, however, pin 296 must be restored to its normalposition, and this is effected by a lever 3| 2 which rotates in unisonwith the grand total key I40 so that upon depression of the grand totalkey I40 with the lever I30 set in the total taking position, a pin 313on the lever 3I2 will engage a tail 3M on the lever 308 and rock thelever 306 clockwise on its pivot to disengage the shoulder 3 from thepin 30?, thereby releasing the lever 304 and permitting the pin 2% toreturn to its operative position under the influence of its spring 30L Alever 3I5 has a nose which is disposed between the shoulder 306 on thelever 304 and a nose M6 on the lever 3I2 so that with the control leverI30 in either the add or subtract position the grand total key I40cannot be depressed. When, however, the control lever I30 is moved tothe total taking position and the lever 303 is rotatedcounter-clockwise, it rotates the lever 3I5 counter-clockwise, removingthe nose thereof from the path of the nose 3 I6 on the lever 3I2.

It will be understood that in taking totals from the item totalizers IIIto H9 the subtraction of the value from the totalizer occurs in thefirst revolution, and the second revolution is an idle revolutionbecause the grand totalizer is not moved into registering position. Onthe other hand, in taking a grand total, the first revolution is an idlerevolution and in the second revolution the value is subtracted from thegrand totalizer.

Printing As previously stated, each item entered into the itemtotalizers and the grand totalizer is printed on the tape I3I (Fig. 1)together with an identifying character to show whether it was added orsubtracted, and in which totalizer it was registered. The totals arealso printed. Be cause of the fact that totals are taken by copying thefigures from the totalizers to the keyboard, totals as well as items canbe printed in 34! on a square shaft 342.

'a common shaft 3%.

the same manner, that is, any figure set in the keyboard is printed whenany of the item totalizer keys E2! to 52s are depressed duringregistering operations, and whenever any of these and the grand totalkey Mt are depressed when taking totals.

Referring to Fig. 2. Each square shaft 159 has a sleeve 338 slidablethereon and rotatable therewith. Integral with each sleeve is a bevelgear 33! which, when the machine is at rest, is in engagement with abevel gear 332. Bevel gears 332 have spur gears 333 integral therewithwhich engage gear sectors 3% pivoted on a common shaft Integral with.each gear sector 334 is a gear sector 34:? engaging a pinion t is to beunderstood that in each order of the selecting mechanism the mechanismjust described is duplicated so that at the outset of the operation thesquare shafts 55% are geared to the transversely extending square shafts36.2 and they remain geared thereto during the digitation phase of thefirst cycle in order to transmit to the shaft 342 differential movementsrespective of the value set in the keyboard.

Prior to the transfer phase in the first cycle, however, all of thebevel gears 33! are disengaged from the bevel gears 332. For thispurpose each sleeve 330 is engaged by an arm 343 secured to Referring toFig. 10, the left end of the shaft 344 has secured thereto a camfollower 3'15 which cooperates with a earn 346 secured to the gear 232.The gear 232 rotates clockwise, as shown in Fig. 10, at one-half thespeed of the main drive shaft 553 so that after the digitation phase ofthe first cycle, cam 345 rocks the follower 3% of the shaft 344counter-clockwise to move the arm 343 (Fig. 2) clockwise therebydisengaging the bevel gears.

Square shafts 342 extend transversely to the right side of the machinewh re, as shown in Fig. 12,. they are connected by pinions 35s to gearsegments 35 l, rotatably mounted on a shaft 352. Each gear segment 355has formed integrally therewith a gear segment engaging a rack (notshown) on a type bar slidable on a shaft 356. Each gear segment 35f isconnected to its type bar 355 by a spring 35'! which maintains the gearsegment and the rack (not shown) in mesh. Mounted on each type bar 3355are individual type 36!} bearing numerals to 9 as shown in Fig. 6. It isto be understood that during the digitation phase of the first cycle thetype bars 355 are differentially displaced amounts corresponding to thevalue in the keyboard so that after the type bars have been set the type359 bearing the required numeral is disposed between a fixed transverseplaten 351 and a hammer 382, there being a hammer 362 for each type bar355.

Before the bevel gears 332 are disengaged the setting of the type barsis retained therein by the following mechanism. Each gear segment (Fig.12) has engaged therewith a pinion 353 (Fig. 14) and an aligner wheel354. All of the aligner wheels 355. are engaged by a common bail 355after the type bars have been set. The bail 355 is connected by a link356 to a gear 235! meshing with the gear 3'58 on a shaft S'ii. The shaft3'?! (Fig. 11) has a gear 3'22 thereon which engages an intermediategear 3'53 which meshes with the gear 37 on the main drive shaft m3.interconnecting the gear 332 and a disk 3'15 on the shaft 3' (Fig. 12)is a rod 378 which is shown in the full cycle position where it engageslever 3% pivoted at 33! on gear sectors 35H.

12 The levers 380 are spring-urged counter-clockwise (Fig. 12') and therod 316 releases the levers 388 so that the gear sectors 355 are free tobe set. At the conclusion of the operation the rod 316 engages thelevers 380 and restores all the gear sectors 35! to their normalposition.

The type hammers 362 are pivotally mounted on a fixed shaft 332. Eachhammer 352 overlies a pin 383 on a bellcrank 38s rotatably mounted onthe shaft 382. A spring 385 is attached at one end to the pin 383 and atthe other end to a pin 386 in the hammer. The bellcrank 384 is connectedby a spring 390 to a fixed rod 391. Each hammer 382 has a hook 392pivoted thereto at 393. When a hook 392 is disposed in active positionit is adapted to be engaged by a bail 394 secured to a shaft 355. Shaft395 has an arm 386 (Fig. 14) secured thereto which is connected by alink 331 to an arm 398 on shaft 31! so that upon rotation of the shaft3H the bail 394 picks up all hooks 392 in the active position and holdsthe hammers 352 connected thereto downwardly, tensioning their springs3% until the hooks slip off the bail 3% and the springs 33!) cause thehammers 362 to strike the type 350. The type strikes the underside ofthe paper tape 13 l. The ribbon 453i? passes around the fixed platen 36!and is disposed between the platen and the upper surface of the paper.The impression is taken from the ribbon and appears on the upper face ofthe paper. This indirect mode of printing is disclosed in theaforementioned Patent No. 2,405,- 562.

The hooks 352 are so arranged that the first two orders are alwaysprinted while the higher orders are printed only up to the firstsignificant figure. For this purpose the hooks 392 in the first twoorders (see Fig. 16) are connected by springs em to pins 462 on thecorresponding hammers. Pins 403 limit their movement. Springs 4M thusserve to hold the hooks 392 in the first two orders in their rearward oractive position where they are always picked up by the bail 394. Thehook Q52 in the third order (see Figs. 13 and 16) has a spring 4H4 whichnormally positions it in the inactive position. On its higher order sidethis hook has an car 405 which cooperates with a pin 405 on the hook 392in the next higher order and all of the hooks in the higher orders aresimilarly provided with ears 4935 on their higher order side, and pins406 on their lower order side. As a result, in the normal position ofthe parts the spring 404 holds not only the hook 392 in the third orderin its inactive position, but also all other higher order hooks becauseof the engagement of the ears 485 with the pins 46%. Associated witheach of the pins 4% is one arm of a bellcrank 401. These bellcranks arerotatably mounted on a shaft 498, and the other arm of each bellcrank isconnected by a spring 499 with a pin 4H] on the associated gear sector35!. In the normal position of the parts, counter-clockwise rotation(Fig. 12) of these bellcranks 401 under the influence of their springsis prevented by pins 4 on the gear sectors viii. Setting of the firstsignificant figure causes rotation of the gear sector 35! in that orderand removal of the pin 4! I, permitting the spring 439 to rotate thebellcrank lii'! which, in engaging the pin 4%, moves the associatedhammer 3% and all lower order hammers into active position. In thismanner printing of ciphers to the left of the first significant figureis avoided.

In order to print a symbol to identify the char- .13 iacter of theoperation, a type bar 420 (Figs. 14 and 16) is provided bearing theplus, minus and asterisk signs. The lever I30 (Figs. 11 and 14) which isset to the add, ubtract and total positions has a pin 42! engaging in aV slot 422 in an arm 423 secured to a shaft 424. Also secured to theshaft 424 (Fig. 14;) is an arm 425 having three recesses 425, 421, 428into which a pin 430 on the type bar 420 enters when the type bar isset. The type bar has integral therewith a rack 43! engaging a gearsegment 432 integral with a gear segment 433 which has a spring 434attached thereto. When the gear segment 433 is released for movement,the spring 434 rotates it clockwise, moving the type bar 420 rearwardly'until the pin 430 seats in one of the recesses 426, 421, 428 whichserves to position the symbol.

In order to identify the totalizer, a type bar 435 (Fig. 16) is providedhaving type from 1 to 9. Type bar 435 is urged rearwardly in the samemanner as the type bar 420 and has a pin 436 thereon which engages oneof the series of steps 431 (Fig. 11) in a plate 438 secured to the shaft305. Shaft 305 (Fig. has an arm 440 thereon to which is secured a spring44l which urges the shaft 305 clockwise in Fig. 10, or counterclockwisein Fig. 2. Disposed beneath each rod I98 in each totalizer framework isa cam arm 442 secured to the shaft 305. The cam arms 442 are so arrangedthat the shaft 305 will be rotated different amounts for differenttotalizers so that the plate 438 is angularly displaced a differentamount for each totalizer thereby serving to differentially stop the pin436 and position the identifying numeral of the totalizer in theprinting line.
